JENS JENSEN, OF RAOINE, XVISCONSIN.

.GRA|N=CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 377,385, dated February '7, 1888.

Application filed July 10, 1887. Serial No. 241,467.

To aZZ whom it may concern:

Be it known that I, JENs JENSEN, of Racine, in the county of Racine, and in the State of Visconsin, have invented certain new and useful Improvements in Doors for GraiuOars; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to doors for grain-cars; and it consists in certain peculiarities of construction and combination of parts,to be hereinafter described with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure 1 represents a side elevation of my invention in operative position; Fig. 2, a section taken online 2 2, Fig. 1; Fig. 3, a detail; and Fig. 4,21. section on line 4 4, Fig. 1.

Referring by letter to the drawings, A represents a portion of a box-ear such as is ordinarily employed for hauling loose grain. To one of the door-posts B, and near the top of the car, I secure a head, 0, that is provided with a vertical groove, a, and a recess or opening, 12, to receive the upper end of a rod, D, the lower end of this rod being stepped in a socket, E, that comes flush with the car-floor. The head 0 is preferably provided with flanges c c at right angles to each other, thus forming a corner-iron that serves to strengthen the door-post B, to which said head may be fast ened.

Secured to a longitudinal timber, F, or side of the car, is an eye, G, that engages the rod D, and serves as an intermediate stay-piece to prevent said rod from being bent, twisted, or warped out of its vertical position.

Secured to one end of the car-door II are irons I-I, bent to encircle the vertical rod D, and journaled in each iron, so as to come against said rod, is a friction-roller, J. The irons I and friction-rollers J form the hinges for the door, and at the same time permit it to be run up or down on the vertical rod D.

Arranged on the journal d of the upper roller, J, outside of the adjacent hinge-iron I, are the vertical flanges e of a hook, K, and the doorposts B B are preferably provided with rubirons L L.

To the floor of the car, adjacent to the door- (No model.)

post 13, is secured a notched plate,-M, that serves as a catch for the door H, and arranged on the latter is a sliding bolt, N, that engages a socket, O, mortised in said post. Supposing that the car is loaded with grain and it is desirable to open the door, the latter is lifted, so that the upper end of the hook K will pass through the groove a and come above the head 0. \Vhen the door is in this position, it is swung around out of the way, the upper end of the hook K resting on the head 0, to retain said door in its elevated position.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a car, of a vertical rod, a vertically-grooved socket-head for the upper end of the rod, a sliding and swinging door operative on said rod, and a hook seeuredto the door and arranged to pass through the groove in the head and come over upon the latter, substantially as set forth.

2. The combination, with a car, of a vertical rod, a door, irons bent to encircle the rod and secured to the door, and friction-rollers journaled in the irons, to come against said rod, substantially as set forth.

3. The combination, with a car, of a vertically-grooved head having flanges at right angles to eachother, to form a corner-iron, a vertical rod having its upper end secured in the head, a sliding door arranged on the rod, and a hook secured to the door and arranged to pass through the groove in the head and come over upon the latter, substantially as set forth.

4. The combination, with a car, of a vertical rod, a door, irons bent to encircle the rod and secured to the door, a hook having vertical flanges secured to the uppermost iron,and a head having a vertical groove for the passage of the hook, substantially as set forth.

In testimony that I claim the foregoing I havehereunto set my-hand, at Racine, in the county of Racine and State of XVisconsin, in the presence of two witnesses.

JENS JENSEN.
